Abstract
In the present study, binary temperature-sensitive magnetic fluids, which are mixtures of temperature-sensitive magnetic fluids (TSMFs) and organic fluids, are utilized in a heat transport device to test its cooling performance and heat transport. In order to do so, the heat transport characteristics of the binary TSMFs and the effects of magnetic fields and inclination angles of the heating section are investigated experimentally. Results show that the coexistence of forced and natural convections, the effect of the gas-bubbles' movement on heat diffusion and the magnetic buoyancy force acting on the binary TSMFs and gas-bubbles affect the heat transport phenomenon in the heat transport device.
